Generally, the arrangement of Taiyuan Travel Agency is that the one-day tour price of Qiaojia Courtyard in Pingyao Ancient City is around 240 yuan.
The price of a two-day tour of Hukou Waterfall, Yao Temple and Sophora japonica is around 450 yuan.
They all left separately. If you want to go to Hukou Waterfall and Pingyao Ancient City, you must go with two tour groups for three days.
There is another way, you can ask the travel agency to arrange a chartered car for you, so you can go, but the price will be much higher.
I suggest you only go to Pingyao Ancient City and Qiao Family Courtyard for a one-day tour. At present, there is no water in Hukou Waterfall, and there is nothing to see. Go to Hukou Waterfall again in May.
